Evolutionary game theory in spatial environments has attracted much interest
from researchers who seek to understand cooperative behaviour among rational
individuals in complex environments. Many models have considered the scenarios
where participant’s interactions are constrained by particular graph
topologies, such as lattices [1]}, [2]}, small-world graphs
[3]}, [4]}, scale-free graphs [5]}, [6]} and,
bipartite graphs [7]}. It has been shown that the spatial
organisation of strategies on these topologies affects the evolution of
cooperation [8]}.
